It features a 1\/2 inch diameter with a 0.120 inch corner radius, five flutes with a variable index geometry, and a 38-degree helix angle that promotes efficient chip evacuation and surface finish quality. The AlCrTiN coating provides high heat resistance and wear resistance, making this tool well-suited for high-speed and dry machining environments. Right-hand cutting and right-hand flute direction are standard. This tool is installed and operated by machinists and CNC programmers working in job shop, production, and toolroom environments.\u003c\/p\u003e\u003cp\u003eThe 311610 is used in vertical and horizontal milling applications where a corner radius profile is required to reduce stress concentrations at the base of a feature or to produce a blended radius at the floor of a pocket or slot. With a 5\/8 inch length of cut and 2-1\/2 inch overall length, it is suited to shallow-to-moderate depth passes in die and mold work, aerospace components, and general precision machining. The centercutting design allows plunge entry directly into the workpiece. Single-end configuration with a 1\/2 inch straight shank for standard collet or end mill holder mounting.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlCrTiN coating for high heat and wear resistance in demanding cutting conditions\u003c\/li\u003e\n\u003cli\u003e5-flute variable index design reduces harmonic vibration and chatter\u003c\/li\u003e\n\u003cli\u003e0.120 inch corner radius for stress-relieved pockets and blended floor transitions\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without pre-drilled entry\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide substrate for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes smooth chip flow and improved surface finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/2 inch collet chucks, end mill holders, or shrink-fit toolholders compatible with a 1\/2 inch straight shank.

Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before mounting or removing the tool. Use a properly sized collet or end mill holder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before production use to confirm proper seating and minimize tool deflection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (63.5 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.1200 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlCrTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.001000 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 311610\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727174697266,"sku":"311610","price":141.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/315c0e8bd9c81399719719f28f161c18.jpg?v=1788674328","url":"https:\/\/voomisupply.com\/products\/accupro-311610-corner-radius-end-mill-1-2-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
